Ventilate the bathroom without windows, that is possible and here you can see how. With these 5 tips it succeeds and you will be master champ at TonyBet. The bathroom is particularly susceptible to mold. To prevent this, only one thing helps: airing. But what if the bathroom was built without windows?

Too much moisture in the apartment leads to mold – and this can attack the building fabric and damage health. To prevent mold from forming on the walls, many bathrooms have windows. These are opened after showering or bathing to let the moist air out. But what to do if the apartment has a bathroom without windows? How do you ventilate these rooms?


In this case, ventilation systems will help. They lead to the outside through a duct and provide air exchange. If the bathroom is not located directly on an exterior wall, it may have a central exhaust air system. This is connected to a ventilation shaft or an unoccupied pipe connection and blows the exhaust air through it to the outside.

Exhaust air systems are mandatory in bathrooms without windows: DIN 18017 and the guidelines of the German states stipulate that windowless rooms must be ventilated by a mechanical system. Landlords:inside must keep the systems in good repair, as clarified by the Munich District Court in a ruling in 2019 maru gujarat.


These additional measures against humidity in the bathroom can help you. You can see a small to-do list, so you never have to struggle with mold again.

Those who struggle with moisture in the bathroom despite ventilation can take the following measures:

  • Dry tiles after showering with squeegee, so that the moisture can not soak into the joints.
  • Dry damp towels in another room. This should not be loaded with moisture. If you have a balcony, you can use it – even in winter.
  • Exchange air: To do this, open one (or more) windows in a room adjacent to the bathroom. Open the intermediate doors, doors to other rooms should be closed. The open windows allow the humid indoor air to be exchanged with the dry outdoor air. The air exchange works especially well when the outside air is colder than the air inside. However, windows should not be left open for too long to prevent the home from cooling down.
  • Use hygrometers to keep an eye on humidity. A relative humidity of 40-70 percent in the bathroom is fine. If the value is above that, you should take countermeasures. A hygrometer is available for a few euros at home improvement stores, such as Obi or Toom.
  • Dehumidifiers can be used if none of the other solutions help to ventilate the bathroom sufficiently without windows. The devices can filter several liters of water from the air. However, electric dehumidifiers consume electricity, thus incurring costs. Chemical dehumidifiers bind humidity in a granulate, so they work without electricity. However, you have to replace the granules regularly, which also costs money.
